Taylor Time Blog: Water Leaks Under Homes — What Every Homeowner Should Know

If you own a home built on a slab or crawlspace, you need to understand one thing: water doesn’t stay put. Once it finds a path, it will travel, and by the time you notice signs inside, the leak may have been going on for months.

How Leaks Start

Most leaks under homes begin small, such as a loose plumbing connection, a cracked drain line, or a pinhole in a supply pipe. Over time, water can saturate the soil beneath the foundation or soak insulation and wood framing in a crawlspace. This leads to musty odors, mold growth, structural decay, and even foundation movement.

Common Signs of a Leak

You don’t have to be an inspector to notice the warning signs. Keep an eye out for:
• Unexplained increase in your water bill
• Constant sound of running water when no fixtures are on
• Warm spots on floors (for homes with hot water lines under slab)
• Soft or spongy flooring near bathrooms or kitchens
• Damp soil, standing water, or fungus under the home
• Moldy or musty odors inside living areas

How Professionals Detect Leaks

As a licensed home inspector, I use moisture meters, infrared cameras, and crawlspace inspections to track moisture patterns and locate hidden leaks. In some cases, a plumber may perform a pressure test or use acoustic leak detection equipment to pinpoint the exact location before repairs.

Why Quick Action Matters

Water under a home is never harmless. Left unchecked, it can:
• Rot joists, subflooring, and sill plates
• Damage insulation and vapor barriers
• Attract termites and other pests
• Create mold and air quality issues
• Weaken the foundation over time

What to Do if You Suspect a Leak

Check your water meter when no fixtures are running. If it’s moving, you have a leak.
Look under sinks and around toilets for small drips.
Inspect your crawlspace or foundation area for dampness or discoloration.
Call a licensed plumber or home inspector for a professional evaluation.

Final Word

Water leaks are one of those problems that never get better with time. Whether you notice a damp crawlspace or a spike in your water bill, deal with it early. A simple inspection today can prevent thousands of dollars in damage later.
